Abstract

This disclosure provides an analog to digital converter comprising n tunnel diode measuring circuits connected at regular intervals to a transmission line. One end of the line is tied to a gate circuit which samples analog voltages under control of a clock signal the other end of the line is terminated in its characteristic impedance. The measuring circuits are connected in accordance with their ordinal numbers to n measuring transmission lines supplying calibrated measuring pulses derived by a pulse generator from the clock signal. In each measuring line, a short circuiting switch is inserted after the first connection of the line to a respective measuring circuit, each switch being connected for control to the digital output of the corresponding measuring circuit.
